Area, Area
Step-by-step explanation:
The rectangle and the circle are connected via this relationship.
Triangle area equals Circle area
2.4=-5y+14.9
We move all terms to the left:
2.4-(-5y+14.9)=0
We get rid of parentheses
5y-14.9+2.4=0
We add all the numbers together, and all the variables
5y-12.5=0
We move all terms containing y to the left, all other terms to the right
5y=12.5
y=12.5/5
y=2+2.5/5
Y=2.5
Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
